-
Shola vegetation
-
Desert vegetation
-

What type of vegetation is commonly found in the semi-arid climate zone of India?
-
Tropical rainforests
-
Temperate grasslands
-
Desert shrubs and cacti
-
Alpine meadows
C
Correct answer
Explanation
The semi-arid climate zone in India supports vegetation adapted to dry conditions, such as desert shrubs, cacti, and thorny bushes.
Which of the following is NOT a type of biodiversity hotspot?
-
Tropical rainforest
-
Coral reef
-
Mediterranean forest
-
Temperate grassland
D
Correct answer
Explanation
Temperate grasslands are not considered to be biodiversity hotspots, as they are not as species-rich as other ecosystems.
Which of the following ecosystems in India is particularly vulnerable to climate change?
-
Himalayan glaciers
-
Coral reefs
-
Sundarbans mangrove forests
-
Western Ghats
Correct answer
Explanation
All of the ecosystems mentioned above are particularly vulnerable to climate change due to their unique characteristics and sensitivity to changes in temperature, precipitation, and sea level.
Which of the following is NOT a type of riverine wetland?
-
Floodplain
-
Marsh
-
Swamp
-
Desert
D
Correct answer
Explanation
Desert is a type of dry ecosystem, not a type of riverine wetland. Floodplain, marsh, and swamp are all types of riverine wetlands.
Which of the following is NOT a type of riverine ecosystem?
-
Floodplain forest
-
Riparian forest
-
Desert
-
Wetland
C
Correct answer
Explanation
Desert is a type of dry ecosystem, not a type of riverine ecosystem. Floodplain forest, riparian forest, and wetland are all types of riverine ecosystems.
Which of the following is NOT a characteristic of desert ecosystems?
-
High temperatures
-
Low precipitation
-
Sparse vegetation
-
High humidity
D
Correct answer
Explanation
Deserts are characterized by low precipitation, high temperatures, and sparse vegetation. High humidity is not a characteristic of desert ecosystems.
Which of the following is an example of a desert plant that has adapted to conserve water?
-
Cactus
-
Palm tree
-
Oak tree
-
Maple tree
A
Correct answer
Explanation
Cacti have adapted to conserve water by storing it in their thick, fleshy stems. Palm trees, oak trees, and maple trees are not desert plants and do not have this adaptation.
Which of the following is an example of a coastal desert?
-
Sahara Desert
-
Gobi Desert
-
Atacama Desert
-
Namib Desert
D
Correct answer
Explanation
The Namib Desert is a coastal desert located in southwestern Africa. It is the oldest desert in the world and is home to a variety of unique plants and animals.
Which of the following is NOT a characteristic of coastal deserts?
-
Low precipitation
-
Moderate temperatures
-
Sparse vegetation
-
High humidity
B
Correct answer
Explanation
Coastal deserts are characterized by low precipitation, sparse vegetation, and high humidity. Moderate temperatures are not a characteristic of coastal deserts.
Which type of forest is most effective at absorbing carbon dioxide?
-
Tropical rainforests
-
Temperate forests
-
Boreal forests
-
Mangrove forests
A
Correct answer
Explanation
Tropical rainforests are the most effective at absorbing carbon dioxide because they are highly productive and have a large biomass.
Which marine ecosystem is characterized by dense underwater forests of kelp?
-
Coral Reefs
-
Mangroves
-
Kelp Forests
-
Seagrass Beds
C
Correct answer
Explanation
Kelp forests are underwater ecosystems dominated by large brown algae known as kelp.
Which marine ecosystem is characterized by high levels of biodiversity and is often referred to as the 'rainforests of the sea'?
-
Coral Reefs
-
Mangroves
-
Kelp Forests
-
Seagrass Beds
A
Correct answer
Explanation
Coral reefs are incredibly diverse ecosystems, supporting a wide variety of marine life and are often compared to rainforests in terms of biodiversity.
Which of the following is a characteristic feature of desert ecosystems?
-
High levels of biodiversity
-
Abundant water resources
-
Sparse vegetation
-
Moderate temperatures
C
Correct answer
Explanation
Desert ecosystems are characterized by sparse vegetation due to the lack of water. Plants in desert ecosystems have adapted to survive in these harsh conditions, often having deep roots to reach underground water sources and thick cuticles to reduce water loss.
Which of the following is not a major type of forest in India?
-
